NetApp, Microsoft and Citrix have teamed up to let Free BSD run natively in Hyper-V. The move makes sense for Microsoft: FreeBSD may not be a major OS player, but W3techs says it still has 1.2 per cent of the web server market. If it enjoys even half of that market share for other servers, that almost certainly means plenty of …
I suppose you could also mention that Citrix uses FreeBSD for their Netscaler load balancer platform (of which they have virtual appliances named VPX).
Though it looks like VPX has been supported on Hyper-V for a couple of years now ?
If that's the case it implies FreeBSD has worked fine for a while, wonder what the new code was about - perhaps performance related or something, maybe native drivers for Hyper-V.
FreeBSD has worked fine in Hyper-V since Server 2008 SP1
I've been building kernel drivers for Hyper-V on FreeBSD for months now. :/
